Japanese watchmaker Seiko and Kojima Productions are collaborating on a new Metal Gear Solid V: The Phantom Pain related merchandise: the Seiko NextAge MGSV TPP Collaboration Watch. This is a similar watch to the one Snake is wearing in the game (though not identical in all features).
Shinkawa was involved in the production as a supervisor and has also designed the packaging.
The watch is limited to 2500 copies, and will cost 45,000 yen excluding taxes (about 375 dollars or 340 euros). It will be released on September 3rd, a day after the Japanese release of the game. It will be available for pre-order at Konami Style starting April 1st.
The watch was also shown during episode 34 of Kojima Station, go here for some still images.
